A Power Bank is a portable charger designed to recharge your electronic devices when you're on the move. Ranging in size from slim, pocket-sized devices up to larger, higher-capacity Power Banks – they can be used to charge smartphones, tablets etc.
Is a power bank worth it?
There are many benefits to buying a high capacity power bank. It allows you to charge your device multiple times over. It is very convenient to have the power bank if you are one that often forgets to charge your device overnight or you travel a lot, making it difficult to always have access to a wall outlet.
